• Quark model
• AdS(5) correspondence
• Light-front Schrodinger equation

We construct a Schrodinger-like equation for the longitudinal wave function of a meson in the valence q (q) over bar sector, based on the 't Hooft model for large-N two-dimensional QCD, and combine this with the usual transverse equation from light-front holographic QCD, to obtain a model for mesons with massive quarks. The computed wave functions are compared with the wave function ansatz of Brodsky and de Teramond and used to compute decay constants and parton distribution functions. The basis functions used to solve the longitudinal equation may be useful for more general calculations of meson states in QCD.
